* develop-olympus:
[task/refactor-db-testcase] Further improve error messages.
[task/refactor-db-testcase] Do not show db password on connect error
[task/refactor-db-testcase] Improve error message of db tests
[task/refactor-db-testcase] Refactor phpbb_database_test_case
Move most of the methods to a separate connection manager class. The
test case creates a manager to handle database creation, schema loading
and more. Most of the methods could be simplified because they can
access shared pdo, config and dbms data.

* develop-olympus:
[task/session-tests] Renamed assertSqlResultEquals and fixed its param order
[task/session-tests] Test additional combinations of session_begin.
[task/session-tests] Added tests for the session class.
Conflicts:
tests/mock/cache.php
Two first simple tests to check functionality of session_begin and
session_create.
Added a mock class for the cache as well as a subclass of session
which has its cookie handling function mocked out to avoid header
sending problems.
PHPBB3-9732
They are now refered to as cache drivers rather than ACM classes. The
additional utility functions from the original cache class have been
moved to the cache_service. The class loader is now instantiated without
a cache instance and passed one as soon as it is constructed to allow
autoloading the cache classes.
